FIELD: engine building.
SUBSTANCE: invention relates to liquid-propellant rocket engines. In liquid-rocket engine chamber mixing head containing outer bottom, housing with rings installed in it with cooling channel and holes for liquid component supply, gaps between which form the gaseous component supply ring channels, the fuel starting nozzle, according to invention end face of rings with cooling channels and holes for supply of liquid component is made in form of wave surface (for example, sinusoid) with magnitude of amplitude of 0.1–0.3 of diameter of cylindrical part of chamber.
EFFECT: invention provides higher reliability of engine operation, eliminating occurrence of high-frequency pressure fluctuations in the chamber.
